The synthesis of diaryl sulfones derivatives through Friedel-Crafts sulfonylation was achieved by using trifluoromethanesulfonic acid as catalyst with arylsulfonyl chlorides and arenes at elevated temperatures. In this procedure, the catalyst and the surplus of arene may well be retrieved and recycled in further batches.
In the presence of triflic anhydride, sulfonylation of arenes with sulfonamides proceeded smoothly in Cl(2)CHCHCl(2) at 80-140 degrees C, which gave rise to the desired products in good to excellent yields. (c) 2008 Elsevier Ltd. All rights reserved.
